#![warn(missing_docs)]
#![cfg_attr(docsrs, feature(doc_cfg))]

//! Define all the tooling necessary to manipulate Mithril certified types from a
//! [Mithril Aggregator](https://mithril.network/rust-doc/mithril_aggregator/index.html).
//!
//! It handles the different types that can be queried to a Mithril aggregator:
//!
//! - [Snapshot][snapshot_client] list, get and download tarball.
//! - [Mithril stake distribution][mithril_stake_distribution_client] list and get.
//! - [Certificates][certificate_client] list, get, and chain validation.
//!
//! The [Client] aggregates the queries of all of those types.
//!
//! **NOTE:** Snapshot download and Certificate chain validation can take quite some time even with a fast
//! computer and network.
//! For those a feedback mechanism is available, more details on it in the [feedback] submodule.
//!
//! # Example
//!
//! Below is an example describing the usage of most of the library's functions together:
//!
//! **Note:** _Snapshot download and the compute snapshot message functions are available using crate feature_ **fs**.
//!
//! ```no_run
//! # async fn run() -> mithril_client::MithrilResult<()> {
//! use mithril_client::{ClientBuilder, MessageBuilder};
//! use std::path::Path;
//!
//! let client = ClientBuilder::aggregator("YOUR_AGGREGATOR_ENDPOINT", "YOUR_GENESIS_VERIFICATION_KEY").build()?;
//!
//! let snapshots = client.snapshot().list().await?;
//!
//! let last_digest = snapshots.first().unwrap().digest.as_ref();
//! let snapshot = client.snapshot().get(last_digest).await?.unwrap();
//!
//! let certificate = client
//!     .certificate()
//!     .verify_chain(&snapshot.certificate_hash)
//!     .await?;
//!
//! // Note: the directory must already exist, and the user running the binary must have read/write access to it.
//! let target_directory = Path::new("/home/user/download/");
//! client
//!     .snapshot()
//!     .download_unpack(&snapshot, &target_directory)
//!     .await?;
//!
//! let message = MessageBuilder::new()
//!     .compute_snapshot_message(&certificate, &target_directory)
//!     .await?;
//!
//! assert!(certificate.match_message(&message));
//! #    Ok(())
//! # }
//! ```
